General Power Tool Safety

Warnings

WARNING Read all safety warnings and all

instructions.

Failure to follow the warnings and instructions

may result in electric shock, fire and/or serious injury.

Save all warnings and

instructions for future reference.

The term "power tool" in the warnings refers to your

mains-operated (corded) power tool or battery-operated

(cordless) power tool.

Work area safety

1. Keep work area clean and well lit. Cluttered or

dark areas invite accidents.

2. Do not operate power tools in explosive

atmospheres, such as in the presence of

flammable liquids, gases or dust. Power tools

create sparks which may ignite the dust or fumes.

3. Keep children and bystanders away while

operating a power tool. Distractions can cause

you to lose control.

Electrical safety

4. Power tool plugs must match the outlet. Never

modify the plug in any way. Do not use any

adapter plugs with earthed (grounded) power

tools. Unmodified plugs and matching outlets will

reduce risk of electric shock.

5. Avoid body contact with earthed or grounded

surfaces such as pipes, radiators, ranges and

refrigerators. There is an increased risk of

electric shock if your body is earthed or grounded.

6. Do not expose power tools to rain or wet

conditions. Water entering a power tool will

increase the risk of electric shock.

7. Do not abuse the cord. Never use the cord for

carrying, pulling or unplugging the power tool.

Keep cord away from heat, oil, sharp edges or

moving parts. Damaged or entangled cords

increase the risk of electric shock.

8. When operating a power tool outdoors, use an

extension cord suitable for outdoor use. Use of

a cord suitable for outdoor use reduces the risk of

electric shock.

9. If operating a power tool in a damp location is

unavoidable, use a ground fault circuit

interrupter (GFCI) protected supply. Use of an

GFCI reduces the risk of electric shock.

Personal safety

10.

Stay alert, watch what you are doing and use

common sense when operating a power tool. Do

not use a power tool while you are tired or under

the influence of drugs, alcohol or medication.

A

moment of inattention while operating power tools

may result in serious personal injury.

11. Use personal protective equipment. Always

wear eye protection. Protective equipment such

as dust mask, non-skid safety shoes, hard hat, or

hearing protection used for appropriate conditions

will reduce personal injuries.

12. Prevent unintentional starting. Ensure the

switch is in the off-position before connecting

to power source and/or battery pack, picking

up or carrying the tool. Carrying power tools

with your finger on the switch or energising power

tools that have the switch on invites accidents.

13. Remove any adjusting key or wrench before

turning the power tool on. A wrench or a key left

attached to a rotating part of the power tool may

result in personal injury.

14. Do not overreach. Keep proper footing and

balance at all times. This enables better control

of the power tool in unexpected situations.

15.

Dress properly. Do not wear loose clothing or

jewellery. Keep your hair, clothing, and gloves away

from moving parts.

Loose clothes, jewellery or long

hair can be caught in moving parts.

3

16.

If devices are provided for the connection of dust

extraction and collection facilities, ensure these are

connected and properly used.

Use of dust collection

can reduce dust-related hazards.

Power tool use and care

17. Do not force the power tool. Use the correct

power tool for your application. The correct

power tool will do the job better and safer at the

rate for which it was designed.

18.

Do not use the power tool if the switch does not turn

it on and off.

Any power tool that cannot be controlled

with the switch is dangerous and must be repaired.

19.

Disconnect the plug from the power source and/or

the battery pack from the power tool before making

any adjustments, changing accessories, or storing

power tools.

Such preventive safety measures reduce

the risk of starting the power tool accidentally.

20. Store idle power tools out of the reach of

children and do not allow persons unfamiliar

with the power tool or these instructions to

operate the power tool. Power tools are

dangerous in the hands of untrained users.

21. Maintain power tools. Check for misalignment

or binding of moving parts, breakage of parts

and any other condition that may affect the

power tool’s operation. If damaged, have the

power tool repaired before use. Many accidents

are caused by poorly maintained power tools.

22. Keep cutting tools sharp and clean. Properly

maintained cutting tools with sharp cutting edges

are less likely to bind and are easier to control.

23. Use the power tool, accessories and tool bits

etc. in accordance with these instructions,

taking into account the working conditions

and the work to be performed. Use of the power

tool for operations different from those intended

could result in a hazardous situation.

Service

24. Have your power tool serviced by a qualified

repair person using only identical replacement

parts. This will ensure that the safety of the power

tool is maintained.

25. Follow instruction for lubricating and

changing accessories.

26. Keep handles dry, clean and free from oil and

grease.

USE PROPER EXTENSION CORD. Make sure your

extension cord is in good condition. When using an

extension cord, be sure to use one heavy enough to

carry the current your product will draw. An undersized

cord will cause a drop in line voltage resulting in loss of

power and overheating. Table 1 shows the correct size

to use depending on cord length and nameplate ampere

rating. If in doubt, use the next heavier gage. The

smaller the gage number, the heavier the cord.

RECIPRO SAW SAFETY

WARNINGS

1. Hold power tool by insulated gripping

surfaces, when performing an operation

where the cutting accessory may contact

hidden wiring or its own cord. Cutting

accessory contacting a "live" wire may make

exposed metal parts of the power tool "live" and

could give the operator an electric shock.

2. Use clamps or another practical way to secure

and support the workpiece to a stable platform.

Holding the work by hand or against your body

leaves it unstable and may lead to loss of control.

3.

Always use safety glasses or goggles. Ordinary eye

or sun glasses are NOT safety glasses.

4. Avoid cutting nails. Inspect workpiece for any

nails and remove them before operation.

5. Do not cut oversize workpiece.

4

6. Check for the proper clearance beyond the

workpiece before cutting so that the blade will

not strike the floor, workbench, etc.

7. Hold the tool firmly.

8. Make sure the blade is not contacting the

workpiece before the switch is turned on.

9. Keep hands away from moving parts.

10. Do not leave the tool running. Operate the tool

only when hand-held.

11. Always switch off and wait for the blade to

come to a complete stop before removing the

blade from the workpiece.

12. Do not touch the blade or the workpiece

immediately after operation; they may be

extremely hot and could burn your skin.

13. Do not operate the tool at no-load

unnecessarily.

14. Always use the correct dust mask/respirator

for the material and application you are

working with.

15. Some material contains chemicals which may

be toxic. Take caution to prevent dust

inhalation and skin contact. Follow material

supplier safety data.
